PROJECT TITLE
Fresno Sanitary Landfill
Scope of Work and Budget for Year 2023 (supplemental) through June 2025
I"ntroduction
Provided below are descriptions of work tasks to be performed by CDM Smith Inc. (Consultant)
on behalf of the City of Fresno (City) as part of ongoing operations at the Fresno Sanitary
Landfill Superfund Site ("FSL" or"Site"). Ongoing activities are being performed as part of
Operable Unit No. 1 (OU-1 — landfill control system operations, maintenance, and reporting) and
OU-2 (groundwater remediation system operations, maintenance, and reporting). The ultimate
objective of the continued work is to achieve regulatory formal closure of the FSL Superfund
Site under the oversight of the U.S. Environmental Protection Agency (EPA).
This scope of work presented below describes work to be performed during the third and fourth
quarters of 2023 and extends through June 2025 (end of City fiscal year 2025). Consultant is
currently performing work for the City under Amendments No. 1 and No. 2 to the existing
agreement. Amendment No. 1 reflected work activities to perform during 2023 to support the
monitoring program, system operations assistance, and ongoing reporting required for the FSL
and the ongoing groundwater remediation. Amendment No. 2 covered work activities for
planning and implementation of the second round of the vapor intrusion (VI) investigation, which
was performed in March 2023. Following submittal of the report in July 2023 which documented
the second round of the VI, EPA has required an additional round of VI investigation to be
performed. This work will be performed during the next construction season (May 1-October 31,
2024) as approved by EPA in their September 26, 2023 email. The scope of work presented
below includes planning and implementation of round 3 of VI investigation activities.
Additionally, this scope of work includes quarterly groundwater sampling activities to be
performed beginning in October 2023. Groundwater sampling field activities had previously
been performed by City staff, who are no longer available to support this effort. The City has
requested support to perform these field activities. Bid period and construction period services
in support of the Landfill Regrading Design #1 is also included in this scope of work.
Additionally, this scope of work includes work activities to be performed during 2023 through
June 2025.
These scope of work activities are a continuation of work performed under the existing contract
with the City (dated 2022) and under Amendment No. 1 (for work performed in 2023) and
Amendment No. 2 (for the Spring 2023 VI investigation). Work described below is defined in
terms of the five project tasks listed below:

Task 2 — Remedial Action Systems Operations Assistance
Objectives
Support the City's high-quality performance of the landfill environmental control systems,
including the landfill cover, landfill gas (LFG) control, and stormwater management systems.
* Assist City staff in the ongoing operations, monitoring, and maintenance of the groundwater
remediation system and the landfill control systems at the FSL.
Activities
Under this task, Consultant will assist the City in ongoing operations and maintenance activities
associated with the groundwater treatment system and the landfill control systems. This task will
consist of on-site and office activities necessary to maintain effective operation of the
groundwater collection and treatment system, the LFG control system, and the function of the
final landfill cover/stormwater management systems. This task includes the following activities:
■ Operable Unit 1 Annual Report (Annual Activity)— Consultant will prepare a report, which is
intended to document operations and maintenance activities associated with the landfill
(LFG) control elements, including the landfill cover, stormwater management, and LFG
control systems. The OU-1 Annual Report, to be submitted to EPA in February 2024 and
February 2025, will address operations during the prior year. The OU-1 Annual Report will
consist of the following elements:
Summary of LFG flare operating data. This summary would include a listing of the LFG
flare downtimes, including downtimes resulting in operation of the GTP in LFG flare
bypass mode.
Compilation of perimeter LFG monitoring probe data.
Assessment of the condition of the landfill cover system and the stormwater
management system. The assessment would rely on information generated during
inspections of the landfill cover and stormwater management system performed by
Consultant and/or City staff. Of particular importance is the inspection scheduled early
fall, prior to onset of rainy weather.
Overview of maintenance activities performed on the landfill control systems and
description of repairs or equipment replacements.
■ Surface Emissions Monitoring (SEM)— Consultant prepared the SEM Work Plan in October
2022, and the City performed SEM in May 2023. City staff will be responsible for performing
the SEM on a quarterly basis, with the next monitoring rounds in October 2023, January
2024, and April 2024. Federal guidelines allow a reduction in frequency to annual monitoring
if methane is not detected above 500 ppm for three consecutive quarters. It is expected that
there will be a single SEM event in 2025. Consultant will be available to provide input to City
staff in terms of refinements to the SEM program at the FSL and to prepare a brief technical
memorandum following each monitoring period. The objectives of the technical
memorandum are to document the SEM program activities and to present the monitoring
data. Each technical memorandum will be submitted to EPA, following draft document
submittal to City staff for review and Consultant incorporation of revisions from City staff.

■ Landfill Inspection and Maintenance Assistance—Activities to be performed under this
subtask will be focused on assisting the City in planning and performing landfill inspection
and maintenance activities.
- Annual Landfill Inspection (Annual Activity)—The annual landfill inspection will be
performed during the Fall of 2023 and Fall of 2024. At the request of the City, additional
inspections may be performed following heavy precipitation events that could impact
landfill control systems function. A description of landfill inspection activities/procedures
is provided below:
• Focus of the inspections will be on the landfill control system elements, including
landfill cover system, surface water management system, and LFG control
system.
• Highlight the need for performing routine maintenance activities related to the
landfill control systems.
• Highlight the need for performing corrective action activities to address damage,
inoperable conditions, or failure of the landfill control systems. The descriptions
will be specific to each of the landfill control system elements.
• Prepare report to document inspection and to describe maintenance, repair, and
corrective actions.
• Identify landfill regrading needs identified as part of the landfill inspections.
- Wet Weather Inspections— Inspections will be performed during wet weather months
(considered to be October through March). City staff will be responsible for performing
these inspections, including completing the inspection form for submittal to Consultant
who will review and submit to EPA.
- Quarterly Inspections—Given overlap with the other scheduled landfill inspections
(Annual and wet weather Inspections, only one quarterly inspection during the year
(June). City staff will be responsible for performing this inspection, including completing
the inspection form for submittal to Consultant who will review and submit to EPA.
■ Annual Evaluation of Extraction Well Performance (Annual Activity) — Consultant will perform
an evaluation of the performance of each extraction well on an annual basis. Performance
factors to be considered during the performance evaluation will include specific capacity
(pumping rate per foot of drawdown) and changes in pumping rate and drawdown over time,
with comparison to historical data.
■ New Well Evaluations (Periodic Activity) — Consultant will perform groundwater modeling
evaluations of proposed new water supply wells (agricultural and residential) in the vicinity of
the FSL. The purpose of the new well evaluations is to assess the potential for impact to the
existing groundwater remediation system at the FSL from operation of proposed new wells.
Under the current arrangement, the County of Fresno, Department of Public Health,
Environmental Health Division (Fresno County) notifies the City when a permit application
for a new or replacement water supply well is submitted in a location within the well
assessment zone. Based on groundwater modeling results, Consultant will either
recommend that the well not be installed or recommend design modifications for the
proposed well (e.g., depth of well, depth of annular seal, and length of screen zone). It is
assumed that Consultant will perform two evaluations per year for the duration of the period
of performance.

Groundwater Modeling- Based on discussions during recent technical meetings with EPA
(most recent was held August 23, 2023), we anticipate that groundwater modeling will be
required to address questions from EPA. In consultation with the City, Consultant will
perform groundwater monitoring in responding to EPA comments/questions. It is assumed
that this task is limited to 100 labor hours during the period October 2023 through June
2025.
Assumptions
SEM event will be performed in October 2023, January 2024, and April 2024. It is assumed
that the City will not detect methane at concentrations above 500 ppb, which will allow the
quarterly monitoring program to be reduced to annual monitoring. Therefore, the cost
estimate was developed with the assumption that three SEM technical memoranda will be
prepared during 2023-2024 and one SEM technical memorandum in. 2025.
With monthly requests from Consultant, City staff will provide Consultant with information
listed below in a timely manner. The requested information constitutes critical information for
reporting to EPA (e.g., Quarterly Progress Reports, OU-2 Annual Performance Monitoring
Report, OU-1 Annual Report).
- Downloads of the SCADA system in Excel with operations data for the groundwater
remediation system (data from extraction well operations and groundwater treatment
plant operations) and for the landfill gas (LFG)flare system (LFG flare operations).
Consultant will compile these data and make necessary assumptions and calculations
for filling data gaps.
- Weekly maintenance summaries for the groundwater remediation system and the LFG
flare.
Deliverables
1. OU-1 Annual Report (Annual Deliverable). A draft report will be submitted to the City for
review. The report will be revised based on review comments from the City and finalized for
submittal to EPA. Two OU-1 Annual Reports will be prepared under this scope of work, with
submittal dates of February 2024 and February 2025.
2. Annual Extraction Well Performance Evaluation Technical Memorandum (Annual
Deliverable). The technical memorandum, which will document the performance evaluation
on each of the groundwater extraction wells, will be submitted to the City. This technical
memorandum is not intended as a formal submittal to EPA. One Extraction Well
Performance Evaluation will be prepared under this scope of work, with a submittal date of
July 2024.
3. New Well Evaluations (Periodic Deliverables). At the conclusion of each new well evaluation
that is performed, a letter to the City will be prepared for submittal to the City which
documents groundwater modeling results and provides well construction recommendations.
4. SEM Technical Memorandum. A technical memorandum will be prepared to document each
quarterly monitoring event. It is expected that three SEM technical memoranda will be
prepared during 2023-2024 and one annual report during 2025.

Task 6 — Landfill Regrading/Landfill Control Systems Repair — Design,
Bid Period, and Construction Period Services (OU-1)
The City began implementation of a Landfill Regrading Program to address differential
settlement that has occurred on the landfill. The Landfill Regrading Program was developed as
two design projects described below:
■ Landfill Regrading Design #1 —The Design #1 addresses settlement along the eastern side
slopes, eastern perimeter drainage channel and eastern access road. Repairs of the landfill
gas control system are also included.
■ Landfill Regrading Design #2— Design #2 addresses settlement of the remaining portions of
the FSL, including the southern, northern, and western side slopes and the top deck of the
landfill. Design #2 activities are not currently included in the scope and budget for 2024.
This scope of work does not include any activities for Design #2 (Subtask 6.2). The descriptions
below address Subtask 6.1 — Design #1.
Subtask 6.1 — Landfill Regrading Program - Design #1: Drainage Channel
Regrading and Gas Control System Maintenance
Subtask 6.1 — Landfill Regrading Program Design #1— Design for the project titled East Slope
Drainage Regrading and Gas System Upgrades Project was initiated in 2021 and completed in
2022 with submittal of the 100% design documents in June 2022.
Objectives
■ Provide bid period and construction period support services associated with construction of
Design #1.
Activities
Bid Period Services

assistance in claims support, and assistance in preparation of a project punch list. It is assumed
that this task is limited to 100 labor hours.
Regorfrrrg
This subtask will consist of preparing a Tech Memo to document the Task 6 construction efforts.
The Tech Memo is intended for submittal to the USEPA. Given that this construction project is a
maintenance project, the report will be less detailed than the Interim Remedial Action Report
that had been prepared to document past remedial action construction activities performed at
the FSL.
Assumptions
• Up to two visits to the FSL by CDM Smith staff during the Bid Period.
■ Up to five visits to the FSL by CDM Smith staff during the Construction Period.
